Happy new decade everyone! A mini post today to record me spending just half an hour in the garage during which I discovered that the heater control unit pipe was completely blocked with rusty crud. I found this when I was offering it up to where it is mounted on the engine and was asking myself how any coolant was supposed to flow through it when there was no hole. A quick prod with an old screwdriver proved that the crud could be dislodged fairly easy and this was also the case with the aperture into the engine water jacket.
I wondered to myself if this was possibly the reason the car overheated when I first fired it up shortly after buying it, and why the fan was set to be on the whole time. What a bodge by the previous owner, but satisfying to find this problem and be a step towards sorting it out.
And finally, this is me, my better half and my in laws at a New Year’s Eve party last night
A big milestone achieved today with the engine and gearbox installed. It was just getting dark as we finished, and we didn’t manage to properly fit the geatbox mountings (a well known MGB challenge), but as my friend noted ‘It looks in’.
This is how it unfolded. The original plan was to install the engine yesterday, but unfortunately in this part of the UK we had a severe rain storm and it just wasnt feasible. Moving the job to today, meant I lost one of my two helpers, who had a work commitment up North. So it was just me and a friend from Church, John, who knows a thing or two about mechanics and is a practical and clever guy who I was confident would get the job done. Question was, would I be enough of an assistant?
First job was to see how to sling the engine. John got on with this while I torqued up the gearbox bolts. We then lifted the engine just to see how it would hang.
Having got the engine rigged up to the crane we had to rotate the engine and car through 180 degrees. The engine crane takes some manouvering. We used spare wooden floor boards as runways for the castors to make it as easy as possible, but even this was tricky, with having to move them around and the crane occasionally falling off the runway. To turn the MG, we had to push it up the drive and onto the road to do a three point turn. An old gentleman was walking his dog and looked curiously at us. He asked ‘What’s wrong with it?’. John replied ‘It hasnt got an engine’. He seemed satisfied with the answer and continued on his slow walk up the road.
As further preparation I jacked up the rear of the car and removed the grille to give us some more room to get the crane as close as possible for maximum reach. We also laid throws around the engine bay and wrapped the gearbox with a sheet and a feed bag as protection against any accidental knocks.
So having done all the preparation, it was time to see if we could do the job.
First attempt at lifting the engine ended in failure. We found that with a single sling we weren’t able to tilt the engine enough by force alone to get anywhere close to the angle we needed to fit into the car. So we rigged up the balance bar which I had been loaned by Corsham Tyre Services. The balance bar has two lifting points connected by a threaded bar which allows you to tilt the load. Cool piece of kit which as it turned out was critical to the job getting done.
Our next set of challenges were around maximising the reach of the crane which was at its absolute limit. We had to release the bonnet struts and lash the bonnet up as high as it would go (see picture above). With the crane at maximum reach, at maximum tilt and very close to the bonnet, it looked as if we would be short of where we would need to be. However, with a bit of shoving and pushing, some very careful manipulation of the crane height and angles, and some light prying, we got the engine close enough to the mounting brackets to get a bolt on each side. Seems easy when I write it now, but it was fairly stressful as the space is really quite tight, especially with the starter motor on, not one of my best ideas. So we had the engine in place, and our focus now turned to the gearbox and the dreaded cross-member.
The cross-member is an awkward piece of design by MG which is well-known for being very difficult to fit. And so it turned out to be. We managed to get one gearbox mounting fitted, but the other side refused to play ball despite our best efforts. Regretfully, we had to bolt up the cross-member with only one mounting properly installed because we were losing the light at this point. A sensible decision, as there was quite a lot of kit to put away, and although it was disappointing to be beaten, we at least had got the main job done and left things in a safe state for future completion.
So thanks John for leading the job today – in the evening, I was invited over to his place, where John’s wife had cooked a delicious spag bol (my wife Helen was away on a school trip to China).
Secondly, thanks to Corsham Tyre Services for lending the lifting kit without which we really would have struggled.
Thirdly, thanks to Austin for his generous loan of the engine crane.
